DETAILED DESCRIPTION

The detailed description set forth below is intended as a description ofvarious configurations of the subject technology and is not intended torepresent the only configurations in which the subject technology may bepracticed. The appended drawings are incorporated herein and constitutea part of the detailed description. The detailed description includesspecific details for the purpose of providing a thorough understandingof the subject technology. However, it will be apparent to those skilledin the art that the subject technology may be practiced without thesespecific details. In some instances, well-known structures andcomponents are shown in block diagram form in order to avoid obscuringthe concepts of the subject technology.

Overall System

FIG. 1 illustrates a simplified diagram of a system 100, in accordancewith various aspects of the subject technology. The system 100 mayinclude one or more client devices 102 (e.g., 102 a, 102 b, 102 c, 102d, 102 e) in communication with a server computing device 112 (server)via either a public network 118 or a corporate network 114. In someaspects, the server 112 is configured to allow remote sessions (e.g.,remote desktop sessions) wherein users can access applications and fileson the server 112 by logging onto the server 112 from a client device102. Such a connection may be established using any of severalwell-known techniques such as the Remote Desktop Protocol (RDP) on aWindows-based server. In some aspects, the client devices 102 maycommunicate with the server 112 using file transfer protocol (FTP),hypertext transfer protocol (HTTP), hypertext transfer protocol secure(HTTPS), or other suitable protocols.

By way of illustration and not limitation, a client device 102 canrepresent a computer, a mobile phone, a laptop computer, a thin clientdevice, a personal digital assistant (PDA), a portable computing device,or a suitable device with a processor. In one example, a client device102 is a smartphone (e.g., iPhone, Android phone, Blackberry, etc.). Incertain configurations, a client device 102 can represent a cashierdevice, an audio player, a game console, a camera, a camcorder, an audiodevice, a video device, a multimedia device, or a device capable ofsupporting a connection to a remote server. In one example, a clientdevice 102 can be mobile. In another example, a client device 102 can bestationary. According to one aspect of the disclosure, a client device102 may be a device having at least a processor and memory, where thetotal amount of memory of the client device 102 could be less than thetotal amount of memory in a server 112. In one example, a client device102 does not have a hard disk. In one aspect, a client device 102 maycomprise flash memory instead of a hard disk. In one aspect, a clientdevice may include one or more client devices.

In a preferred aspect, a client device 102 is a specific-purpose clientdevice designed for a specific-purpose (rather than a general purpose).In a preferred aspect, a client device 102 is not a conventionalpersonal computer (PC). In one aspect, a specific-purpose client devicemay be designed to perform one or a few pre-defined, dedicatedfunctions. For example, a specific-purpose client device may be designedto perform less than 10 dedicated functions, less than 5 dedicatedfunctions, less than 3 dedicated functions, or 1 dedicated function. Aspecific-purpose client device may be, for example, a client devicedesigned as a cashier machine at a department store, a client devicedesigned to carry out specific tests or measurements, a client devicedesigned to carry out a specific medical application for diagnosisand/or treatment of a patient, etc. A specific-purpose client devicepreferably includes a write-filter that is enabled during its normaloperation so that if a user (e.g., a cashier, not an administrator)changes any configuration of an embedded image of the client device,such change does not persist across a reboot.

In one aspect, a server 112 may represent a computer, a laptop computer,a computing device, a database, an in-house server, a repository server,a configuration application server, a domain name system (DNS) server, adynamic host configuration protocol (DHCP) server, a virtual machine(e.g., VMware® Virtual Machine), a desktop session (e.g., MicrosoftTerminal Server), a published application (e.g., Microsoft TerminalServer) or a suitable device with a processor. In a preferred aspect, aserver 112 is stationary. In another aspect, a server 112 can be mobile.In yet another aspect, a server 112 can be embedded. In certainconfigurations, a server 112 may be any device that can represent aclient device. In a preferred aspect, the server 112 is not a client. Inone aspect, a server 112 may include one or more servers, or functionsof one or more servers.

In one example, a first device is remote to a second device when thefirst device is not directly connected to the second device. In oneexample, a first remote device may be connected to a second device overa communication network such as a Local Area Network (LAN), a Wide AreaNetwork (WAN), and/or other network for remote operations.

When a client device 102 and a server 112 are remote with respect toeach other, a client device 102 may connect to a server 112 over apublic network 118 and/or the corporate network 114, for example, via amodem connection, a LAN connection including the Ethernet or a broadbandWAN connection including DSL, Cable, T1, T3, Fiber Optics, Wi-Fi, or amobile network connection including GSM, GPRS, 3G, WiMax or other remotenetwork connection. The public network 118 or the corporate network 114can be a LAN network, a WAN network, a wireless network, the Internet,an intranet or other remote network. In one aspect, the public network118 or the corporate network 114 may include one or more routers forrouting data between client devices and/or servers. A remote device(e.g., client device, server) on a network may be addressed by acorresponding network address, such as, but not limited to, an Internetprotocol (IP) address, an Internet name, a Windows Internet name service(WINS) name, a domain name or other system name. These illustrate someexamples as to how one device may be remote to another device. But thesubject technology is not limited to these examples.

According to certain aspects of the present disclosure, the terms“server” and “remote server” are generally used synonymously in relationto a client device, and the word “remote” may indicate that a server isin communication with other device(s), for example, over a networkconnection(s).

According to certain aspects of the present disclosure, the terms“client device” and “remote client device” are generally usedsynonymously in relation to a server, and the word “remote” may indicatethat a client device is in communication with a server(s), for example,over a network connection(s).

In one aspect of the disclosure, a “client device” may be sometimesreferred to as a client or vice versa. Similarly, a “server” may besometimes referred to as a server device or vice versa.

In one aspect, the terms “local” and “remote” are relative terms, and aclient device may be referred to as a local client device or a remoteclient device, depending on whether a client device is described from aclient side or from a server side, respectively. Similarly, a server maybe referred to as a local server or a remote server, depending onwhether a server is described from a server side or from a client side,respectively. Furthermore, an application running on a server may bereferred to as a local application, if described from a server side, andmay be referred to as a remote application, if described from a clientside.

In one aspect, devices placed on a client side (e.g., devices connecteddirectly to a client device(s) or to one another using wires orwirelessly (e.g., using Bluetooth having a short range such as 35 feetor Infrared)) may be referred to as local devices with respect to aclient device and remote devices with respect to a server. Similarly,devices placed on a server side (e.g., devices connected directly to aserver(s) or to one another using wires or wirelessly (e.g., usingBluetooth having a short range such as 35 feet or Infrared)) may bereferred to as local devices with respect to a server and remote deviceswith respect to a client device.

In some aspects, the server 112 may comprise a repository server 104, aDNS server 106, a DHCP server 108, and a configuration applicationserver 110. Although the server 112 is shown as comprising all of theseservers, one or more of these servers may be placed outside the server112. In some aspects, one or more of these servers may be combinedtogether as a single server. In some aspects, the server 112 may also bereferred to as an in-house server because the server 112 may primarilyoperate to communicate with clients 102 a, 102 b, 102 c, and 102 d overa private network such as the corporate network 114. Boundary 122 mayrepresent the boundary of this private network in which the in-houseserver 112 communicates with the clients 102 a, 102 b, 102 c, and 102 d.In some aspects, client device 102 c and 102 d are on the same domain(e.g., as represented by the dotted line 115).

In some aspects, at least a portion of the server 112 may be accessiblefrom the public network 118. For example, as shown in FIG. 1, therepository server 104 is accessible from the public network 118. Thus,the client device 102 e may communicate with the server 112 (e.g., therepository server 104) via the public network 118.

According to various aspects of the subject technology, the clients 102may each be running a windows-based embedded image, such as any of theWindows Embedded family of operating systems (e.g., Windows EmbeddedCompact, Windows Embedded Standard, Windows Embedded Enterprise, WindowsEmbedded POSReady, Windows Embedded NAVReady, Windows Embedded Server,etc.) or other suitable embedded images.

In general, an embedded image may comprise a write-filter that mayprevent one or more changes applied to the embedded image frompersisting across a reboot of a client device running the embeddedimage. For example, an embedded image may comprise a write filter toallow one or more changes applied to the embedded image with thewrite-filter enabled, to be discarded when the client device is shutdown. In some embodiments, the term “shut down” may refer to shuttingdown a machine. In some preferred embodiments, the term “shut down” mayrefer to shutting down a machine. In another aspect, it may includelogging off from a machine. In some embodiments, as used herein, theterm “reboot” or “restart” may include situations in which a user logsoff and logs back into a client device, or a client device is shut downand then powered back on. In one example, if a user applies a newwallpaper to an embedded image running on a particular client device,the new wallpaper does not remain on the embedded image after thatparticular client device has rebooted.

The write-filter may be enabled to ensure that a user does not make anypermanent changes (e.g., changes that persist across a reboot) to anembedded image of a client device. Enabling the write-filter isbeneficial because it allows an administrator to maintain a uniformconfiguration for all the embedded images of the client devices in aparticular system. If a user makes changes to an embedded image of oneof the client devices, then only that particular client device needs tobe rebooted to reset that embedded image back to the originalconfiguration that is uniform with the other embedded images of theother client devices. Another benefit of enabling the write-filter isthat it may prevent harmful changes from being applied permanently(e.g., applied across reboot) to an embedded image of a client device.For example, if a user of a client device accidentally downloads a virusthat causes harmful changes to an embedded image of the client device,then only that client device needs to be rebooted to reset the embeddedimage back to the original configuration that was not harmed by thevirus.

However, because of the write-filter being enabled, making a desiredchange that persists across reboot to an embedded image may bedifficult. According to some approaches, in order to apply, to anembedded image, a change that persists across reboot, manualinstallation of software drivers and/or a firmware update of theembedded image is performed to create a customized embedded image havingthe desired change. The customization may typically occur at the serverside (e.g., at the server 112), and the entire customized embedded imageis deployed to a client (e.g., the client device 102). Thus,customization of an embedded image may involve transferring an entirecustomized embedded image from a server 112 to a client device 102and/or installing the entire customized image on the client device 102.However, an embedded image can be large in size. For example, Windowsembedded images may need a minimum flash size of 2 gigabytes (GB) (e.g.,for the Windows Embedded Standard 2009) and a maximum of 4 GB (e.g., forthe Windows Embedded Standard 7). Thus, transferring and installingimages at such sizes may be impractical, especially when desired changesare frequent and/or relatively minor or when it involves a large numberof client devices.

For example, in a large cashier system comprising over 100 cashiermachines as client devices, if an administrator wants to install a newcashier program on each embedded image running on each cashier machine,then the administer may need to create a customized embedded imagehaving the new cashier program at a server, and then transfer thecustomized embedded image, from the server, to each cashier machine forinstallation. If the customized embedded image is large in size, thentransferring this image to each of the 100 cashier machines would becumbersome. Furthermore, if the administrator desires to make frequentchanges, then a new customized embedded image may need to be transferredto each cashier machine each time a change is made.

According to various aspects of the subject technology, after boot up ofa client device 102 is initiated, a change may be automatically appliedto an embedded image of the client device 102 without intervention by auser of the client device 102, thereby making the change appear to theuser to be persistent across a reboot of the client device 102. Thus,aspects of the subject technology obviate reinstallation of an entireembedded image with the change onto the client device 102, and theproblem of downloading and/or installing large images onto the clientdevice 102 may be avoided. According to certain aspects, a configurationfile may be used to apply such a change to the embedded image. Theconfiguration file may contain information related to one or moredesired changes to be applied to the client device 102. For example, theconfiguration file may contain instructions to apply the one or moredesired changes, parameters related to the one or more desired changes,driver information related to the one or more desired changes,application information related to the one or more desired changes,and/or other suitable information. In some aspects, a client device 102may download a configuration file from a server 112 and/or apply, to theembedded image of the client device 102, a configuration change based onthe configuration file each time the client device 102 boots up. In onepreferred aspect, transferring the configuration file and applying aconfiguration change in this manner is critical because any changes madeaccording to the configuration file may appear to be persistent to auser of the client device 102 even though the changes may not beretained on the client device 102 when the client device 102 shuts downor is logged off (because of an enabled write-filter). Such anarrangement may make the client device 102 independent andself-provisioning, and therefore, transferring and/or installing largecustomized images onto the client device 102 may be advantageouslyavoided.

According to certain aspects, the configuration file may beautomatically obtained from a server 112. For example, the configurationfile may be stored in the repository server 104. In some aspects, therepository server 104 may be a part of the configuration applicationserver 110. In some aspects, the configuration file may be automaticallyobtained from the remote repository server 104 or a configurationhistory folder (e.g., 416 in FIG. 4) stored on the client device 102. Insome aspects, the configuration file may be a default configurationfile. In some aspects, the obtained configuration file may be comparedto a previous configuration file that was last used to apply one or morechanges (associated with the previous configuration file) to theembedded image. When the changes are successfully applied to theembedded image, such changes may be referred to as last successfullyapplied changes. For example, if a change is a modification of thescreen resolution to 1680×1050 pixels, and if the client device supportssuch a resolution, then the change would be successfully applied. Insome aspects, a last successfully applied change may be understood asthe change is compatible with, or is supported by, the embedded imageand/or a client device 102. If the obtained configuration file is thesame as the previous configuration file, then the last successfullyapplied change is re-applied, and it would appear to the user that thechange persists across reboot of the client device 102.

According to certain preferred aspects, providing an option of applyinga last successfully applied change is beneficial because it ensures thatat least one configuration change can be applied to an embedded image,especially if a new change that is desired to be applied is notcompatible with, or is not supported by, the embedded image and/or theclient device 102. Furthermore, providing an option of applying a lastsuccessfully applied change is beneficial because it can allow a user torevert back to the last successfully applied change, especially if a newchange that was applied is no longer desired.

According to various aspects of the subject technology, a configurationfile may be an extensible markup language (XML) configuration file orany other suitable files. In a preferred aspect, a configuration file isan XML configuration file. In some aspects, an XML configuration filemay refer to an XML-based configuration file. In some aspects, an XMLconfiguration file may comprise some or all of the following types ofsettings: 1) remote desktop connections settings, 2) device settings, 3)operating system (OS) settings, and 4) common settings. The remotedesktop connections settings, which may also be referred to asconnections tags, may define settings for remote desktop protocol (RDP),independent computing architecture (ICA), VMware View, and othersuitable remote desktop connections. The device settings may definesettings for displays, keyboards, mice, networks, audio, power, wirelessconnections, or other suitable settings of a client device 102. The OSsettings section may define settings for Aero, Firewall, a web browser(e.g., Internet Explorer (IE) or other suitable web browsers), one ormore clocks, or other suitable settings of a client device 102.

According to certain aspects, a configuration file may conform to asuitable schema. For example, an XML configuration file may conform toan XML schema definition (XSD) file. XSD can be used to express a set ofrules to which an XML document (e.g., an XML configuration file)conforms in order to be considered valid according to that schema. Insome preferred aspects, using an XML configuration file is essentialbecause it allows the XML configuration file to be validated against theXSD file to ensure that the XML configuration file is in a proper formatthat is compatible and/or supported by a client device. The properformat can allow a configuration change based on the XML configurationfile to be applied correctly to an embedded image of the client device.Without such a proper format, it may not be possible to apply theconfiguration change correctly. In some aspects, validating the XMLconfiguration file using the XSD file before the XML configuration fileis transferred and/or applied can prevent a XML configuration file in animproper format from being unnecessarily transferred and/or applied,thereby beneficially saving resources and time.

Overall Methods

FIG. 2 illustrates an example of a method for applying a change to anembedded image of a client device such that the change would appear to auser of the client device to be persistent across a reboot of the clientdevice, in accordance with various aspects of the subject technology.Method S200 may comprise creating a configuration file (S202),retrieving a configuration file (S204), and applying a configurationfile (S206). Aspects of the subject technology allow a client device 102to be independent and self-provisioned by downloading a configurationfile (e.g., an XML configuration file) automatically from a server 112(e.g., from a repository server 104), and applying one or moreconfigurations and/or installing applications/drivers based on thedownloaded configuration file for customization of the embedded image.In some aspects, management software for customization of an embeddedclient configuration and customization of firmware may be reduced oreliminated. Aspects of the subject technology also reduce the usage ofhigh bandwidth and time by not transferring large entire image filesover a network.

FIG. 3A illustrates an example of a method (e.g., also referred to asMethod A-1) for creating a configuration file, in accordance withvarious aspects of the subject technology. Method S300 a may comprisecapturing client settings of a client device 102 (S302 a) and creating aconfiguration file based on the captured client settings (S304 a). Insome aspects, method S300 a may comprise an optional process ofvalidating the configuration file (S306 a). For example, an XSD schemafile may be used to validate an XML configuration file. In some aspects,method S300 a may comprise storing the configuration file (S308 a). Forexample, the configuration file may be exported to a storage location,such as a universal serial bus (USB) drive, another client device 102, arepository server 104, a server 112 or another location. In onepreferred aspect, storing the configuration file is advantageous becauseit allows the configuration file to be accessed by more than one clientdevice 102. Thus, the same configuration as specified in theconfiguration file can be applied to different client devices 102 bystoring the configuration file and distributing the same configurationfile to different client devices 102.

FIG. 3B illustrates an example of a method (e.g., also referred to asMethod A-2) for creating a configuration file, in accordance withvarious aspects of the subject technology. Method S300 b may comprisecreating a configuration file using a configuration application module.In some aspects, the configuration application module may be an editorfor creating and/or editing configuration files. In some aspects, theconfiguration application module may provide a user interface for a userto create and/or edit a configuration file. In some preferred aspects,the configuration application module may beneficially allow the user tovisualize a configuration change before the configuration applicationmodule is used to create the configuration file that reflects theconfiguration change. For example, the user can use the configurationapplication module to visualize a new display resolution for aparticular client device before using the configuration applicationmodule to create a configuration file that reflects the new displayresolution. This configuration file may then be downloaded by otherclient devices, which can apply the new display resolution to theirrespective embedded images based on the configuration file. In someaspects, method S300 b may comprise an optional process of validatingthe configuration file (S306 b). For example, an XSD schema file may beused to validate an XML configuration file. In some aspects, method S300b may comprise storing the configuration file (S308 b), such as storinga configuration file in a configuration application server 110, arepository server 104, a server 112, a client device 102, a USB drive,or another location. In a preferred aspect, method 300 b may store aconfiguration file in a configuration application server 110, arepository server 104, or a server 112, which can be accessed by some orall of client devices 102.

FIG. 3C illustrates an example of a method for retrieving aconfiguration file, in accordance with various aspects of the subjecttechnology. According to process S301 c, if a desired configuration fileis to be retrieved remotely, then process S302 c (e.g., also referred toas Method B-1), process S302 d (e.g., also referred to as Method B-2),and/or process S302 e (e.g., also referred to as Method B-3) may beutilized. Otherwise, process S310 c (e.g., also referred to as MethodB-4) may be utilized. Method B-1 may comprise attempting to retrieve aconfiguration file using DHCP (e.g., using DHCP server 108). Method B-2may comprise attempting to retrieve a configuration file using DNS(e.g., using the DNS server 106). Method B-3 may comprise attempting toretrieve a configuration file (e.g., a configuration file on a server112) based on local registry values on a client device 102. Method B-4may comprise attempting to retrieve a default configuration file thatmay be used to apply a default configuration to the embedded image. Adefault configuration file can be a factory default configuration fileor another configuration file that is saved locally on the client device102. A locally saved configuration file may be on the client device 102or on a storage device that is locally attached to the client device 102(e.g., flash memory, USB drive, a removable hard disk drive, etc.). Inone preferred aspect, having a default configuration file is beneficialbecause it can ensure that at least a certain configuration can beapplied to an embedded image based on the default configuration file,especially if another configuration file cannot be retrieved and/orapplied. For example, a new configuration file may specify newconnections settings to be applied to an embedded image of a clientdevice. However, if the new configuration file cannot be retrieved, thendefault connections settings specified in the default configuration filecan be applied instead.

In one example, configuration data may be transferred from the server112 to a client device 102, and then be applied on the client device102. The configuration data may be transferred using any of Method B-1,Method B-2, and/or Method B-3 (preferably in this order, or in anotherorder). Otherwise, Method B-4 may be used. For example, if a clientdevice 102 fails to connect to the server 112 using DHCP, DNS or localregistry values, then configuration settings from a factory defaultconfiguration file may be applied. According to certain aspects, amodule that implements method S300 c may be a part of a module referredto as Hagent_UI.exe.

FIG. 3D illustrates an example of a method (e.g., also referred to asMethod C-1) for applying a configuration file, in accordance withvarious aspects of the subject technology. Method S300 d may compriseapplying settings based on a configuration file. In some aspects, amodule that implements method S300 d may be a part of a module referredto as ClientApp.dll. In some aspects, the ClientApp.dll may be a COMlibrary that may take a configuration file as input. Tags from theconfiguration file may be read and the appropriate applicationprogramming interfaces (APIs) may be used to apply most of the settingscontained in the configuration file. In some aspects, if APIs are notavailable, a direct registry writing method may be used (e.g., in thecase of VMware View and ICA connections).

FIG. 3E illustrates an example of a method (e.g., also referred to asMethod C-2) for applying a configuration file, in accordance withvarious aspects of the subject technology. Method S300 e may comprisechecking a reset tag contained in a configuration file (S302 e) andapplying settings based on the configuration file (S304 e). Method S300e may be useful for implementing state-based provisioning of embeddedclient configurations.

In some aspects, a configuration file may specify whether to reset aprevious state of the embedded image. If the configuration filespecifies a reset be applied, then a default configuration is applied tothe embedded image before a configuration change based on a newconfiguration file (e.g., a retrieved configuration file) is applied tothe embedded image. This is beneficial in situations where a completelynew configuration is desired while an old configuration is not neededanymore. For example, if a user of a client device changes from a firstjob to a second job within the same company but retains the clientdevice for use, then the client device can be reset to completely removeany applications on the client device that were directed to the firstjob. A new configuration (e.g., adding applications directed to thesecond job) can then be applied to the client device. In some aspects,if the configuration file does not specify a reset, then theconfiguration change based on the new configuration is applied to theembedded image while disallowing the default configuration from beingapplied to the embedded image. Applying the new configuration whiledisallowing the default configuration from being applied is beneficialbecause it may allow new changes to be appended to an existingconfiguration of the embedded image.

FIG. 3F illustrates an example of a method (e.g., also referred to asMethod C-3) for applying a configuration file, in accordance withvarious aspects of the subject technology. Method S300 f may comprisecomparing a retrieved configuration file to a last successfully appliedconfiguration file (S302 f) and applying settings based on thecomparison (S304 f). For example, if the retrieved configuration file isthe same as the last successfully applied configuration file, a previousconfiguration change is applied to the embedded image. The previousconfiguration change may be based on the last successfully appliedconfiguration file. If the retrieved configuration file is differentfrom the last successfully applied configuration file, then a newconfiguration change is applied to the embedded image. The newconfiguration change may be based on the retrieved configuration file.

Client Device

FIG. 4 illustrates a simplified block diagram of a client device, inaccordance with various aspects of the subject technology. A clientdevice 102 may comprise some or all of the following: a configurationgeneration module 430, a validation file 406, a retrieval module 408, areset check module 410, a configuration comparison module 412, an applysettings module 414, a configuration history folder 416, a defaultconfiguration file 418, an application module 422, a driver module 424,an operating system module 426, and hardware components 428. Theconfiguration generation module 430 may comprise one or both of: aconfiguration capture module 402 and a configuration application module404. The operating system module 426 may preferably include awrite-filter 420, which may contain an exclusion list. In some aspects,the reset check module 410, the configuration comparison module 412,and/or the apply settings module 414 may be a part of ClientApp.dll. Themodules and/or components of the client device 102 may be incommunication with one another. In some aspects, the hardware components428 may comprise various interface devices, and the modules of clientdevice 102 are further in communication with the various user interfacedevices via a human interface devices (HID) connection. The userinterface devices may include one or more output devices (e.g., one ormore of a display, a speaker, or other audio, image or video outputdevices) and one or more input devices (e.g., one or more of a keyboard,a mouse, a trackball, a microphone, a stylus, a touch screen, a touchpad, a pen, a tablet, or other audio, image or video input devices). Themodules may also be in communication with the public network 118 or thecorporate network 114 via a network connection.

In a preferred embodiment, the modules (e.g., 402 through 426) areimplemented in software (e.g., subroutines and code). In anotherembodiment, some or all of the modules may be implemented in hardware(e.g., an Application Specific Integrated Circuit (ASIC), a FieldProgrammable Gate Array (FPGA), a Programmable Logic Device (PLD), acontroller, a state machine, gated logic, discrete hardware components,or any other suitable devices) and/or a combination of both. Additionalfeatures and functions of these modules according to various aspects ofthe present disclosure are further described in the disclosure.

In one example, an embedded image of a client device 102 may comprisethe operating system module 426 and some or all of the following:modules 422, 424, 408, and 414.

In another example, an embedded image of a client device 102 maycomprise the operating system module 426 and some or all of thefollowing: modules 422, 424, 408, 414, and 402. In another example, anembedded image of a client device 102 may comprise the operating systemmodule 426 and some or all of the following: modules 422, 424, 408, 414,402, 404, 406, 410, and 412. In another example, an embedded image of aclient device 102 may comprise the operating system module 426 and someor all of the following: modules 402, 404, 406, 408, 410, 412,414, 416,418, 422, and 424.

According to some approaches, to mass deploy thin client firmwarethrough management software, a customized firmware image may need to becreated as a package. A write-filter of the image may need to bedisabled, software/drivers may need to be installed, appropriateconfigurations may need to be set, and the write-filter may then need tobe enabled. After this process, the firmware on the client may need tobe pulled from a remote server. This firmware image may be of a largesize and may need to be pushed to all the appropriate clients using thecustomized firmware change.

To prevent this process of a large firmware from being pushed onmultiple clients over a network, drivers/applications to be installedmay be specified in a configuration file. In some aspects, theapplications may also be stored along with the configuration file. Assoon as a client boots up, a retrieval module (e.g., Hagent_UI.exe) maydownload the configuration file and use an apply settings module (e.g.,ClientApp.dll) to parse the configuration file, check for differences(e.g., deltas) between a previous configuration file and the newlydownloaded configuration file, and download and install an appropriateapplication/driver.

Configuration Application Server

FIG. 5 illustrates a simplified block diagram of a configurationapplication server, in accordance with an aspect of the presentdisclosure. A server 110 may comprise a configuration application module504, a validation file 506, and an operating system module 508, all ofwhich can be in communication with one another. The server 110 may becommunicatively coupled with the corporate network 114 via a networkinterface, for example. These modules can be implemented in software,hardware and/or a combination of both. In a preferred embodiment, theyare implemented in software. Features and functions of these modulesaccording to various aspects are further described in the presentdisclosure.

Retrieving a Configuration File

FIGS. 6A through 8B illustrate examples of different methods ofretrieving a configuration file (e.g., Methods B-1, B-2, B-3). Aconfiguration file may be retrieved from a repository server where theconfiguration file is stored. In one aspect, a repository server may beany server, a client, any computing device, a database, or any storagedevice.

FIG. 6A illustrates an example of a method for retrieving aconfiguration file (e.g., Method B-1), in accordance with variousaspects of the subject technology. Method S600 may comprise obtaininginformation regarding a repository server 104 and a configuration file,and parameters utilizing DHCP (S602). For example, this information andparameters may be obtained from a DHCP server 108. Method S600 maycomprise facilitating establishing a connection to the repository server104 (S604) and retrieving the configuration file from the repositoryserver 104 (S606). In some aspects, a retrieval module 408 may be usedto implement method S600.

FIG. 6B illustrates an example of an implementation of the method shownin FIG. 6A, in accordance with various aspects of the subjecttechnology. According to certain aspects, a retrieval module 408 (e.g.,Hagent_UI.exe) may be launched by the operating system module 426 afterclient drivers are loaded. The retrieval module 408 may use multiplemethods to identify the repository server 104, which may contain adesired configuration file. In some aspects, Method B-1 may comprise aDHCP option tag method in which it makes use of DHCP client APIs andInternet Protocol Helper API (IPHLPAPI) functions to retrieve the belowmentioned DHCP options:

“DHCPServerTag”=“161” for server IP (e.g., IP address of a repositoryserver where a configuration file is located) “DHCPPathTag”=“162” forthe location of the configuration file in the server“DHCPUsernameTag”=“184” for a username to be used for authentication“DHCPPasswordTag”=“185” for a password for the username to be using forauthentication “DHCPProtocolTag”=“183” for the type of protocol to beused in downloading the configuration file

The retrieval module 408 may also validate the DHCP tag values. In someaspects, the server IP may be needed in order to implement Method B-1.Depending on the protocol tag, port values may be fixed. If the DHCP hasFTP as a protocol, then the port considered may be 21. Port values of 80and 443 may be considered in the case of HTTP and HTTPS, respectively.If the username tag is not set, then anonymous login may be considered.If a protocol tag is not configured, then HTTP may be considered bydefault. In some aspects, retrieval module 408 may make sure that evenif certain tags are not set, default values for those fields may be used(see, e.g., S1306 in FIG. 13). The foregoing tag values and port valuesare presented as examples. It is understood that other suitable valuesmay be used.

FIG. 7A illustrates an example of a method for retrieving aconfiguration file (e.g., Method B-2), in accordance with variousaspects of the subject technology. Method S700 may comprise obtaininginformation regarding a repository server 104 and a configuration file,and parameters utilizing DNS (S702). For example, the information andparameters may be obtained from a DNS server 106. Method S700 maycomprise facilitating establishing a connection to the repository server104 using a Uniform Resource Locator (URL) (e.g., as obtained from theDNS server 106). Method S700 may comprise retrieving the configurationfile from the repository server 104 (e.g., using the URL to locate therepository server 104). In some aspects, the retrieval module 408 may beused to implement method S700.

FIG. 7B illustrates an example of an implementation of the method shownin FIG. 7A, in accordance with various aspects of the subjecttechnology.

In some aspects, a first one of Method B-2 may comprise a DNS servicerecord lookup. An administrator can configure a DNS server (e.g., theDNS server 106) to provide server and port number for a service thatmay, for example, be referred to as “_wyseconfigserver._tcp.” Multipleconfiguration repository server/port values can be provided. Theretrieval module 408 may access them in order, according to the weightand priority associated with each entry. Since the DNS server may notsupply a protocol string associated with each server/port entry, theretrieval module 408 may try HTTP as a protocol if port number is 80.Otherwise, it may try HTTPS and then HTTP for all other port numbers. Iflookup for “_wyseconfigserver._tcp” fails, retrieval module 408 may try“_wyseconfigserver._tcp” plus a domain name, and then each sub-domainname. For example, if the domain name is x.y.z, the retrieval module 408may issue a DNS service location lookup using the following names inorder until the DNS server returns a valid answer:

1. _(—) wyseconfigserver._tcp 2. _(—) wyseconfigserver._tcp.x.y.z 3._(—) wyseconfigserver._tcp.y.z 4. _wyseconfigserver._tcp.z

In some aspects, if the retrieval module 408 is unable to get a validanswer to DNS service record lookup requests, then the retrieval module408 may implement another method. In this regard, a second one of MethodB-2 may comprise a DNS host name lookup. An administrator can configurethe DNS server to provide server IP for a host name (e.g.,“wyseconfigserver”). Since the DNS server may not supply a protocolstring nor a port number, the retrieval module 408 may use HTTPS on port443 first. If this fails, the retrieval module 408 may use HTTP on port80. If lookup for “wyseconfigserver” fails, the retrieval module 408 maytry “wyseconfigserver” plus a domain name, and then each sub-domainname. For example, if the domain name is x.y.z, the retrieval module 408may issue DNS host name lookup on the following names below until theDNS server returns a valid answer:

1. wyseconfigserver 2. wyseconfigserver.x.y.z 3. wyseconfigserver.y.z 4.wyseconfigserver.z

If the retrieval module 408 receives any valid answer for either the DNSservice record lookup or the DNS hostname look up, the retrieval module408 will attempt to download the configuration file using the serverdetails that it received from either of these methods.

FIG. 8A illustrates an example of a method for retrieving aconfiguration file (e.g., Method B-3), in accordance with variousaspects of the subject technology. Method 5800 may comprise obtaininginformation regarding a repository server and a configuration file, andparameters from a local registry of the client device 102 (S802). Method5800 may comprise facilitating establishing a connection to therepository server 104 (e.g., using the information and the parametersfrom the local registry) (S804). Method 5800 may comprise retrieving theconfiguration file from the repository server 104 (S806). In someaspects, the retrieval module 408 may be used to implement method 5800.

FIG. 8B illustrates an example of an implementation of the method shownin FIG. 8A, in accordance with various aspects of the subjecttechnology. According to certain aspects, if connection to the server112 fails with the methods mentioned in FIGS. 6A, 6B, 7A, and 7B, theretrieval module 408 may fall back to settings in the local registry ofthe client device 102. The remote server values may be stored in thelocal registry, and the retrieval module 408 may use these values toaccess the server 112 in order to retrieve the configuration file. Ifthe retrieval module 408 fails to connect to the server 112 using thelocal registry values, then configuration settings from a factorydefault file (e.g., default configuration file 418) that is embeddedwith the client device 102 may be applied (e.g., Method B-4).

Applying a Configuration File

FIG. 9A illustrates an example of a method for applying a configurationfile (e.g., Method C-2), in accordance with various aspects of thesubject technology. In some aspects, the apply settings module 414and/or the reset check module 410 may be used to implement method S900.Method S900 may comprise checking a reset tag in the retrievedconfiguration file (S902). The reset tag may have a value of “1” tocommand the previous state of the configuration of the client device 102to be reset, or a value of “0” to command no reset (i.e., the previousstate of the configuration of the client device 102 does not need to bereset). According to process S904, if the reset tag value is not “0,”then a default configuration file is applied (S906) before a retrievedconfiguration file is applied (S908). If the reset value is “0,” then aretrieved configuration file is applied while disallowing the defaultconfiguration file from being applied (S910). Although the reset tagvalues of “1” and “0” are described, it is understood that othersuitable values may be used.

FIG. 9B illustrates an example of an implementation of the method shownin FIG. 9A, in accordance with various aspects of the subjecttechnology.

According to certain aspects, a reset feature or state-basedprovisioning feature may help a client device 102 to be reset to factorysettings, which may be predefined in the client device 102. The resetfeature may be enabled by setting a reset tag to “1” in theconfiguration file. When this reset tag is set, the apply settingsmodule 414 may first set a default configuration using a defaultconfiguration file present in the client device 102 and then apply theconfiguration in the configuration file, which may be downloaded asmentioned in FIGS. 3C, 6A, 6B, 7A, 7B, 8A, and 8B. Thus, the clientdevice 102 may be ensured to always have settings that are mentioned inthe configuration file.

According to certain aspects, the reset tag may remove all RDPconnections (or other suitable connection settings), view settings, andweb browser settings (e.g., Internet explorer favorites) in addition toresetting the client device 102 and its OS configurations. Below is anexample of how the reset tag may be represented in XML:

<common>   <commonSettings>     <reset>0</reset>   </commonSettings></common>

The reset tag may help with state-based application of a clientconfiguration. In some aspects, a client configuration can either simplyappend to an existing configuration state of a client device 102, orcompletely reset an existing state of the client device 102 to factorydefaults, and then apply a new configuration.

FIG. 10A illustrates an example of a method for applying a configurationfile (e.g., Method C-3), in accordance with various aspects of thesubject technology. In some aspects, the apply settings module 414and/or the configuration comparison module 412 may be used to implementmethod S1000 to apply various settings as specified in the configurationfile. Method S1000 may comprise comparing the retrieved configurationfile with a last successfully applied configuration file (S1002). Insome aspects, the last successfully applied configuration file may bestored in the configuration history folder 416. The configurationcomparison module 412 may compare the retrieved configuration file withthe last successfully applied configuration file. If these two files arethe same, then the last successfully applied configuration file isapplied (S1004 and S1006). If these two files are different, then theretrieved configuration file is applied (S1004 and S1008). For example,the apply settings module 414 may be used to apply either the lastsuccessfully applied configuration file or the retrieved configurationfile. FIG. 10B illustrates an example of an implementation of the methodshown in FIG. 10A, in accordance with various aspects of the subjecttechnology.

FIG. 11A illustrates an example of a method for applying settings basedon a configuration file (e.g., Method C-1, S304 d, S304 e, S304 f), inaccordance with various aspects of the subject technology. For example,the apply settings module 414 may be used to implement method S1100 toapply various settings as specified in the configuration file. MethodS1100 may comprise loading the configuration file (S1102). Method S1100may comprise parsing the configuration file based on a particular group(S1104). For example, the configuration file may be parsed for aparticular group of settings related to the connections settings, thedevice settings, the OS settings, the common settings, etc. Method S1100may comprise applying the settings based on the particular group(S1106). For example, if the particular group of settings is related tothe connections settings, then the apply settings module 414 may applythe connections settings specified in the configuration file. MethodS1100 is advantageous because it may allow for a specific group ofsettings to be applied at a time. In one example, if a user only wantsto apply, to an embedded image of a client device, a particular group ofsettings specified in a configuration file instead of all the settingsspecified in the configuration file, method S1100 may allow the user toapply only the settings for that desired particular group of settings.FIG. 11B illustrates an example of an implementation of the method shownin FIG. 11A, in accordance with various aspects of the subjecttechnology. In some aspects, FIG. 11B illustrates a customization ofclient device 102 firmware by application of configurations.

FIG. 12A illustrates an example of a method for applying a configurationfile (e.g., Method C-1, S304 d, S304 e, S304 f), in accordance withvarious aspects of the subject technology. For example, the applysettings module 414 and/or the configuration comparison module 412 maybe used to implement method S1200 to install drivers and/or applicationsbased on the various settings as specified in the configuration file.Method S1200 may comprise loading the configuration file (S1202). MethodS1200 may comprise parsing the configuration file based on a particulargroup (S1204). Method S1200 may comprise applying the settings based onthe particular group, such as by installing a driver and/or anapplication based on the particular group (S1206).

As an example of an implementation of method S1200, the apply settingsmodule 414 may load a configuration file and parse the configurationfile for a particular group of settings related to drivers orapplications to be installed on the client device 102. The applysettings module 414 may be configured to determine if the configurationfile specifies a new version of a driver or an application to beinstalled. The configuration comparison module 412 may be configured tocompare the new version of the driver or the application to a previousversion of the driver or the application, respectively. If the newversion is different from the previous version, then the apply settingsmodule 414 is configured to: determine if the write-filter is enabled;disable the write-filter if it is enabled; and install, on the clientdevice 102, the new version of the driver or the application while thewrite-filter is disabled. Doing so may advantageously allow the newversion of the driver (e.g., driver module 424) or the application(e.g., application module 422) to remain on the client device 102 evenif the client device 102 is restarted or shut down. FIG. 12B illustratesanother example of an implementation of the method shown in FIG. 12A, inaccordance with various aspects of the subject technology.

FIG. 13 illustrates an example of a method for retrieving aconfiguration file and applying the retrieved configuration file, inaccordance with various aspects of the subject technology. In someaspects, the retrieval module 408 and the apply settings module 414 mayimplement method S1300. As shown by method S1300, a hierarchy ofconnection methods may be used to connect to the server 112 to retrievea configuration file. For example, an attempt to retrieve theconfiguration file may use DHCP or DNS. If these connection methods arenot successful, then repository server information from a local registryof the client device 102 may be used to attempt to retrieve theconfiguration file. If this fails, then a default configuration file isapplied. Although a specific hierarchy is shown in FIG. 13, the subjecttechnology is not limited to this hierarchy. Other suitable hierarchieshaving more or less connection methods and/or different arrangements maybe utilized to retrieve the configuration file.

Installation of Software Modules

FIG. 14A illustrates an example of installing software modules on aclient device to allow process S202, process S204, and/or process S206to be automatically executed on boot up of the client device 102, inaccordance with various aspects of the subject technology. Thesesoftware modules (or components) may be applied to an embedded imagerunning on a client device 102, and may include folders, functions (orsubroutines or code), and other components used for implementing processS202, process S204, and/or process S206. As a result of installing thesecomponents onto the embedded image, these components may remain on theembedded image even if the client device 102 is shut down or restarted.This is because these components are placed into an exclusion list. Thewrite filter of the embedded image does not discard components placedinto the exclusion list when the client device 102 is restarted or shutdown. For example, the configuration history folder 416 may be installedon the embedded image. Thus, any files (e.g., previously appliedconfiguration files) that are stored in this folder may remain on theclient device 102 even if the client device 102 is restarted or shutdown.

According to certain aspects, installing the configuration historyfolder 416 on the embedded image of the client device 102 is beneficialbecause it allows previous configuration files stored in theconfiguration history folder 416 to be compared with a newly retrievedconfiguration file while obviating the need to retrieve the previousconfiguration files from a location different from the client device102. Such an arrangement may also obviate the need to store the previousconfiguration files at the different location in order to preserve ahistory of the configuration changes made to the embedded image if theclient device 102 is restarted or shut down.

In one example, a user interface application module, which may sometimesbe referred to herein as Pyramid.exe, may be installed on the embeddedimage of the client device 102 to provide a user interface to allow auser to implement process S202, process S204, and/or process S206. FIG.14B illustrates an example of an implementation of the method shown inFIG. 14A, in accordance with various aspects of the subject technology.

Examples of Screenshots

FIGS. 15A and 15B illustrate examples of screenshots of a user interfaceapplication module 1500 that a user may use to implement process S202,process S204, and/or process S206, in accordance with various aspects ofthe subject technology. In some aspects, the top horizontal window maybe a status window, which may denote a present active configurationbeing implemented. It may also display the progress of exporting orimporting a configuration file. In some aspects, the user interfaceapplication module 1500 may provide import configuration functionality,export configuration functionality, access to a configuration history(e.g., configuration history folder 416), and/or other advanced options.In some aspects, the advanced options may allow a user to push aconfiguration file. In some aspects, the advanced options may allow auser to configure DHCP tag options or other connection settings.According to certain aspects, the user interface application module 1500may comprise a configuration capture module 402 and a portion of aretrieval module 408. The user interface application module 1500 mayhave access to a configuration history folder 416 and display thecontents (e.g., a list of configuration files stored under theconfiguration history folder) to a user. The user interface applicationmodule 1500 may be utilized to implement at least portions of processesS202, process S204, and/or process S206.

FIG. 15A illustrates an example of locally importing a configurationfile, in accordance with various aspects of the subject technology. Insome aspects, Method B-4 (e.g., S310 c) may comprise importing a defaultconfiguration file, such as from a USB drive. For example, activatingthe import configuration functionality may bring up the screenshot shownin FIG. 15A. Two options may be available, either local or remote. Whenthe local option is selected, the controls under the local option maybecome enabled while the controls under the remote option may becomedisabled. Under the local option, a user (e.g., an administrator) canapply configuration settings from a configuration file onto a clientdevice 102. To select the configuration file to import, the user mayclick on the browse button (e.g., the button with three dots) which mayopen a file-open dialog. The user can select a USB pen drive (if pluggedin) also as a source. Once the configuration file is selected, anApplyparserSettings function may be called and implemented by the applysettings module 414. At the bottom of the top horizontal window, astatus message may be displayed while settings are beingapplied/imported.

When the remote option is selected, the controls under the remote optionbecome enabled and the controls under local option become disabled.Selecting the remote option may make the client device 102 function in astand-alone mode. The user can select either FTP, HTTP, or HTTPs as theprotocol to be used. For example, the default FTP path may be<ftproot>\Wyse\WES7, if no path is specified in the path field. If thepath is mentioned in the user module 1500, then the configuration filemay be located under <ftproot>\Wyse\WES7\<UIPath> path, for example. Ifa local user has logged in to the client device 102, then theconfiguration file downloaded from a remote FTP server may be namedWes7Config.xml, for example. If the login is a domain login, then the<user>.xml file may exist in that FTP path.

In the case of HTTPs, a web server (e.g., a configuration applicationserver 110) may have webDav installed. A virtual directory calledPyramid, for example, may be created. This may be the default context.The virtual directory may be nothing but an alias to a path. On theserver, the Pyramid virtual directory can be c:\ConfigMgr, for example.Under the virtual path, another directory named Wyse\WES7, for example,may be created.

In the user interface application module 1500, if no path is mentioned,then a default path may be taken, such as c:\ConfigMgr\Wyse\WES7. If theadministrator desires a different path, the different path may becreated under c:\ConfigMgr\Wyse\WES7, for example. The customized paththat the administrator has created may be entered under the path fieldin the user interface application module 1500.

According to certain aspects, if a user desires to persist settingsacross reboot, then a “Persist settings across reboot” option should beselected. If the user desires to persist a locally existingconfiguration file (e.g., preferably on the client device 102), then thelocal option should be checked, and a recently imported/appliedconfiguration file may be applied on every boot.

In some aspects, the “Save Settings” button may save the settings intoregistry. This is useful if the user just wants to set the client device102 for remote download and import. If the remote option is selected andthe “Import” button is clicked, then the configuration file may bedownloaded and imported immediately. If the “Persist settings acrossreboot” option is selected, then the configuration file may bedownloaded and imported on every login (or on every boot). In someaspects, a password may be encrypted and stored in registry. If theusername and password paths are empty, then anonymous login may beconsidered.

FIG. 15B illustrates an example of exporting a configuration file(utilizing, for example, Method A-1), in accordance with various aspectsof the subject technology. A configuration file may be created bycapturing settings of a client (e.g., S302 a). In some aspects, theconfiguration capture module 402 may capture the settings of a client.For example, the configuration file may be created by taking a“snapshot” of the current settings of a client, and then creating theconfiguration file based on the captured client settings (e.g., S304 a).According to certain aspects, the created configuration file may becompared with a validation configuration file (e.g., the validation file406) to verify that the created configuration file is in a proper formataccording to the validation configuration file (S306 a). Theconfiguration file may then be exported (e.g., S308 a), as shown in FIG.15B.

According to certain aspects, clicking on the “Export Configuration”button may display the screenshot of the user interface applicationmodule 1500 shown in FIG. 15B. If a user wants to store a current deviceconfiguration into a configuration file, then the Export Configurationoption is to be selected. The user can click on the browse button, whichmay open a “Save As” dialog box. The destination can be any folderwithin a configuration management folder installed as a component (e.g.,as discussed with respect to FIGS. 14A and 14B) (not the configurationhistory folder 416) or on any external USB device (if plugged in).Exporting the configuration file may be useful, for example, when aconfiguration of a first client device 102 is desired to be copied ontoa second client device 102. Thus, the configuration file of the firstclient device 102 can be exported and then applied to the second clientdevice 102.

FIG. 16 illustrates an example of creating a configuration file (e.g.,Method A-2), in accordance with various aspects of the subjecttechnology. In some aspects, the configuration application module 404and/or 504 may be used to create and/or edit a configuration file. Insome aspects, the configuration application module 404 and/or 504 mayprovide a management user interface, for example as shown in FIG. 16, toallow a user to adjust various settings specified in the configurationfile. For example, the configuration application module 404 and/or 504may be used to adjust display settings such as a wallpaper of anembedded image and/or the resolution of the display of the embeddedimage. Furthermore, as discussed above, the configuration applicationmodule 404 and/or 504 may beneficially allow a user to visualize aconfiguration change before the configuration application module 404and/or 504 is used to create the configuration file that reflects theconfiguration change.

FIG. 17 illustrates an example of a screenshot of a desktop of a clientdevice, in accordance with various aspects of the subject technology.For example, a configuration file may be downloaded to the client device102 in order to change the wallpaper 1700. In some aspects, this changemay appear to a user of the client device 102 to persist across a rebootof client device 102. Other settings of the embedded image may bechanged, including, but not limited to, connection settings, displaysettings, application settings, and driver settings. In this example, auser interface application module (e.g., Pyramid.exe) displays “ImportConfiguration,” where “Remote” is selected, and an administrator canpreset the type of protocol to be used, the IP address of a repositoryserver, the port number, the path where a configuration file is locatedin the repository server, a username and a password.

FIG. 18 is a conceptual block diagram illustrating an example of asystem, in accordance with various aspects of the subject technology. Asystem 1801 may be, for example, a client device (e.g., client device102) or a server (e.g., server 112, 104, 106, 108, 110). The system 1801may include a processing system 1802. The processing system 1802 iscapable of communication with a receiver 1806 and a transmitter 1809through a bus 1804 or other structures or devices. It should beunderstood that communication means other than busses can be utilizedwith the disclosed configurations. The processing system 1802 cangenerate audio, video, multimedia, and/or other types of data to beprovided to the transmitter 1809 for communication. In addition, audio,video, multimedia, and/or other types of data can be received at thereceiver 1806, and processed by the processing system 1802.

The processing system 1802 may include a processor for executinginstructions and may further include a machine-readable medium 1819,such as a volatile or non-volatile memory, for storing data and/orinstructions for software programs. The instructions, which may bestored in a machine-readable medium 1810 and/or 1819, may be executed bythe processing system 1802 to control and manage access to the variousnetworks, as well as provide other communication and processingfunctions. The instructions may also include instructions executed bythe processing system 1802 for various user interface devices, such as adisplay 1812 and a keypad 1814. The processing system 1802 may includean input port 1822 and an output port 1824. Each of the input port 1822and the output port 1824 may include one or more ports. The input port1822 and the output port 1824 may be the same port (e.g., abi-directional port) or may be different ports.

The processing system 1802 may be implemented using software, hardware,or a combination of both. By way of example, the processing system 1802may be implemented with one or more processors. A processor may be ageneral-purpose microprocessor, a microcontroller, a Digital SignalProcessor (DSP), an Application Specific Integrated Circuit (ASIC), aField Programmable Gate Array (FPGA), a Programmable Logic Device (PLD),a controller, a state machine, gated logic, discrete hardwarecomponents, or any other suitable device that can perform calculationsor other manipulations of information.

A machine-readable medium can be one or more machine-readable media.Software shall be construed broadly to mean instructions, data, or anycombination thereof, whether referred to as software, firmware,middleware, microcode, hardware description language, or otherwise.Instructions may include code (e.g., in source code format, binary codeformat, executable code format, or any other suitable format of code).

Machine-readable media (e.g., 1819) may include storage integrated intoa processing system, such as might be the case with an ASIC.Machine-readable media (e.g., 1810) may also include storage external toa processing system, such as a Random Access Memory (RAM), a flashmemory, a Read Only Memory (ROM), a Programmable Read-Only Memory(PROM), an Erasable PROM (EPROM), registers, a hard disk, a removabledisk, a CD-ROM, a DVD, or any other suitable storage device. Thoseskilled in the art will recognize how best to implement the describedfunctionality for the processing system 1802. According to one aspect ofthe disclosure, a machine-readable medium is a computer-readable mediumencoded or stored with instructions and is a computing element, whichdefines structural and functional interrelationships between theinstructions and the rest of the system, which permit the instructions'functionality to be realized. In one aspect, a machine-readable mediumis a non-transitory machine-readable medium, a machine-readable storagemedium, or a non-transitory machine-readable storage medium. In oneaspect, a computer-readable medium is a non-transitory computer-readablemedium, a computer-readable storage medium, or a non-transitorycomputer-readable storage medium. Instructions may be executable, forexample, by a client device or server or by a processing system of aclient device or server. Instructions can be, for example, a computerprogram including code.

An interface 1816 may be any type of interface and may reside betweenany of the components shown in FIG. 18. An interface 1816 may also be,for example, an interface to the outside world (e.g., an Internetnetwork interface). A transceiver block 1807 may represent one or moretransceivers, and each transceiver may include a receiver 1806 and atransmitter 1809. A functionality implemented in a processing system1802 may be implemented in a portion of a receiver 1806, a portion of atransmitter 1809, a portion of a machine-readable medium 1810, a portionof a display 1812, a portion of a keypad 1814, or a portion of aninterface 1816, and vice versa.

Example of Implementation of Subject Technology

According to certain aspects, process S202, process S204, and/or processS206 may be run as stand-alone applications. In one example, the userinterface application module 1500 does not support editing of aconfiguration file. In one example, the user interface applicationmodule 1500 does not support filtering of settings. In some aspects, theuser interface application module 1500 may be provided as a controlpanel applet (e.g., Pyramid.exe) that is bundled along with an embeddedimage. In some aspects, a default name for the configuration file may beWesCfg.xml. In some aspects, a default configuration file (for factorydefaults) and an active configuration file may be used.

In some aspects, a workflow of the subject technology may present twoscenarios, one as the control panel applet scenario, and another as astand-alone scenario. In the control panel applet scenario, the controlpanel applet can be used to: 1) capture settings from a device and writeit to a configuration file residing locally or on a USB pen drive; and2) apply the settings read from the configuration file residing locallyor on the pen drive onto a device. Clicking on a “Capture” button of thecontrol panel applet may perform the capture settings functionality, andclicking on an “Apply” button of the control panel applet may performthe apply settings functionality.

In the stand-alone scenario, DHCP option tags may be set on a properDHCP server (e.g., DHCP server 108) or a proxy DHCP server. Once theclient device 102 boots up, the retrieval module 408 may query the DHCPtag options and download the configuration file from the repositoryserver 104 using HTTP. Once the file is downloaded, the apply settingsmodule 414 may call an export function (e.g., ClientApp.dll's exportedfunction) to apply the settings on to the client device 102. A fileserver path can be configured using a user interface (e.g., the userinterface application module 1500) present on the client device 102. TheUI may take the file server path along with a port number to specifywhether it will be HTTP or HTTPS. According to certain aspects, theconfiguration file can be derived from capturing the client device 102settings or built from scratch using the configuration applicationmodule 404 and/or 504.

According to certain aspects, the user interface (e.g., a user interfaceapplication module 1500) may provide the following functionality: a)apply to client device 102 the settings from the a configuration file;b) save the client device 102 settings to a configuration file (e.g.,capture settings); c) reset client device 102 to a defaultconfiguration; d) provide a status output; and e) provide configurationhistories, which may sometimes be referred to herein as snapshots.

According to certain aspects, the apply settings functionality maycomprise importing a configuration file and/or reading settings from theconfiguration file and applying the settings to the client device 102.The capture settings functionality may comprise writing the capturedsettings to a configuration file and/or exporting the settings. In someaspects, a no-filtering option may be available. According to certainaspects, the reset functionality may comprise applying default settingsto the client device 102 internally, which means the settings of thedefault configuration file (e.g., may be named WyseDefCfg.xml) isapplied to the client device 102. In some aspects, the provideconfiguration histories functionality may comprise displaying a list ofconfiguration histories (e.g., snapshots) present on the client device102. A user interface may be provided that will provide an option tocreate a snapshot and/or to revert to a snapshot.

According to certain aspects, the apply settings module 414, the resetcheck module 410, and/or the configuration comparison module 412 mayimplement ClientApp.dll and export the following functions:ReadDeviceSettingstoXML; ApplyParserSettings; RevertToSnapshot;ListSnapshots. The ReadDeviceSettingstoXML function may read a clientdevice 102's settings and write it to a configuration file. The filenamemay be passed as a parameter. The ApplyParserSettings function may readsettings from a configuration file (which is passed as a parameter), andapply the settings to the client device 102. These two functions may becalled, for example, by the control panel applet as well as from theretrieval module 408 during the retrieval of configuration settings. TheClientApp.dll may be used by the configuration application module 404and/or 504.

In some aspects, the RevertToSnapshot function may take a snapshotfilename as an input parameter, and in turn, call theApplyParserSettings function. The ListSnapshots function may return thelist of all snapshot files that are residing on the client device 102.

According to certain aspects, an XSD file may be used to express a setof rules to which an XML document (e.g., an XML configuration file) mayconform in order to be considered valid according to that schema. TheXSD file may be named as WESTypes.xsd, for example.

In some aspects, the retrieval module 408, which may includeHagent_UI.exe, may be modified to query for DHCP options tags todownload the configuration file from a repository server (e.g.,repository server 104) and apply the settings onto the client device102.

According to certain aspects, the configuration file may be an XML file.In some aspects, the XML file can have three main sections: 1)connections section; 2) device configuration section; and 3) an OSconfiguration section.

The connections section may comprise settings related to RDP, ICA, viewtypes of connections, and other suitable connections. Examples ofsettings for RDP connections include:

An operating system that may support the subject technology may includeWES 7.

Example of Implementation of Subject Technology

Aspects of the subject technology enable small businesses (SMBs) to havea lightweight application to manage Windows-based thin clients. Toachieve this objective, SMBs may perform four activities: 1)configuration management; 2) imaging; 3) packaging; and 4) scheduling.Aspects of the subject technology provide configuration management forSMBs. One objective of configuration management is for informationtechnology (IT) administrators to easily configure their Windows basedthin clients and get them configured for their users in the least amountof time possible. Currently, this may be done via customizations in theimage, which may be pulled and then deployed. This can become timeconsuming because image files (e.g., Windows-based image files) arelarge. In addition, customization changes may occur frequently per user,and hence, this consuming process may need to be repeated. Aspects ofthe subject technology provide configuration management, wherein only asingle image from the factory is installed onto the thin clients, whileall customizations may be pushed from a single configuration file ratherthan an entire image.

According to certain aspects of the subject technology, a configurationmanager may provide an out-of-box experience, supportability, andpersonalization. With respect to the out-of-box experience, upon ITadministrators receiving embedded thin clients (e.g., Windows embeddedthin clients), customers are able to boot directly into Windows, andhave all global configurations pushed onto the Windows thin clients,from either a local or a remote source. A customer may also be able tocreate a configuration of their choice, by exporting an alreadyconfigured image (via OS) or by using a configuration editor application(e.g., Configuration Application Module 404 and/or 504). In someaspects, the user or IT administrator does not have to update the imageto get any general functionality working.

With respect to supportability, an IT administrator may be able to keepsupporting changes in global or user configurations throughout thesupport lifecycle of a thin client. This may also apply to anyconfiguration changes needed once the support lifecycle for a particularuser is over. Features are provided that allow for the IT administratorto easily keep track of any configuration changes made on a particulardevice. Furthermore, in addition to configurations related to thedevice, the IT administrator may also change policies on the client thatare configuration manager specific to allow for flexibility and faulttolerance.

With respect to personalization, upon a user logging into his/her ITenvironment, thin clients may gather domain-joined user specificprofile's configurations, either locally and/or from a network. Thegranularity of OS, device, and network settings may allow for the userto have a completely personal experience on a thin client. The user maybe productive the moment the user logs onto the thin client because theuser-specific corporate or preferred configurations may have alreadybeen applied with little or no down-time.

The following scenarios may be implemented by the subject technology. Ina first scenario, an administrator has three thin clients in hispossession. He opens one thin client and configures this client as hedesires (e.g., he may change the wallpaper, RDP connecting via TS, andIE favorites). He can export the configuration file and place it on anFTP server (which can be, for example, the repository server 104 and/orthe configuration application server 110). He can then open the othertwo clients, connect them via an Ethernet cable and power the twoclients up. The remaining two clients may pick the configuration postedon the FTP server through DHCP.

In a second scenario, an administrator has three thin clients that arepowered up and already domain joined. Three separate configuration filesfor three users, respectively, have already been created. Theseconfiguration files have different wallpapers, RDP connections (throughTS), and IE favorites from one another. The administrator may place theconfiguration files in respective user's specific folders on an FTPserver (which can be, for example, the repository server 104 and/or theconfiguration application server 110). He may log in to the threeclients as three different users. Each of the three clients may pick upthe user configuration specific to the user.

In a third scenario, an administrator may receive a support request froma user to add a new browser favorite and to lower the display resolution(e.g., to 1280×1024 pixels). The administrator may obtain the specificuser configuration file, open it up using the configuration capturemodule 504, change the display resolution to the desired displayresolution, and add in the web browser favorite. The administrator maysave this configuration, and place the corresponding configuration filein the user's specific folder on an FTP server (which can be, forexample, the repository server 104 and/or the configuration applicationserver 110). The administrator may then ask the user to log off and login again. The updated user settings may then be picked up by the thinclient of the user using DHCP.

In a fourth scenario, an administrator may receive another supportrequest from the same user in the third scenario. The user may not likethe new resolution and request the old resolution to be re-applied. Theadministrator may then ask the user to open the control panel applet(e.g., the user interface application module 1500), click on theconfiguration history tab, click on the previous configuration history,and hit apply in order to return the user's settings back to theprevious configuration.

In a fifth scenario, a user has a mobile thin client and would like toaccess his configuration from his home network. To achieve this, thespecific user's configuration file is placed on an HTTP server (on DMZ)by the administrator (e.g., this contains the same configuration as theuser.xml.) The user may log onto his thin client (e.g., which may be alaptop) and wait for the client to connect over wireless to the homenetwork. The new updated user settings may be picked up by the mobilethin client by HTTPS on the home network.

In a sixth scenario, a user now has changed his office locationpermanently and no longer needs the thin client he is using. Thus, theadministrator may take back the client. The administrator may configurethe same client for another new user. The administrator may open up astand-alone configuration manager (e.g., the configuration applicationmodule 404 and/or 504) and make relevant changes for that specific newuser (e.g., settings related to RDP, IE, the wallpaper). Theconfiguration file, as created or edited by the stand-aloneconfiguration manager, may indicate that the thin client wipe out anyprevious settings before applying the settings from this particularconfiguration file. The administrator may copy the configuration fileonto a USB key, open the control panel applet, select the importconfiguration option, select the local option, specify the path of theconfiguration file, and click on the ‘Import’ button. In this case, theexisting thin client configuration may be wiped out, and the newconfiguration may be applied locally from a USB key.

According to certain aspects, a Windows thin client may obtain and applyconfigurations from remote locations (e.g., FTP server and/or HTTPserver) via DHCP, DNS, and/or other suitable methods. In addition, anadministrator may be allowed to place the location of the FTP or HTTPserver via an IP address or a friendly name. An appropriate message(e.g., a balloon tip at the bottom right of a system tray of an OS) maybe displayed to the user when a configuration is being applied (andhence the system state is being changed).

In some aspects, DHCP may be used by default when obtainingconfigurations from remote locations. If DHCP does not work via thedefault option tags, then the location (e.g., via the IP address or thefriendly name) specific in the client may be used. If even the locationspecified in client does not work, then local default settings may beapplied.

According to certain aspects, a thin client may also have the abilityfor an administrator to configure the client locally using userinterfaces provided by the operating system and to export thatconfiguration locally onto a flash or a USB drive.

According to certain aspects, a configuration manager, by default, maybe able to push updated configurations to an already configured device.These updates may be subsets of a full configuration. When pushingupdated configurations, only those settings that are part of the updatemay change without changing the overall state of the device. In someaspects, configurations being pushed on thin clients may also be able toreset (e.g., ‘wipe-out’) the existing configuration on the thin clientsand then apply the new configurations. The particular configuration maydepend on the ‘reset’ tag that comes from the configuration definitionfile. These features may be implemented, for example, using method S900.

In some aspects, the configuration history may be exposed to anadministrator per thin client. This may be the last five successfullyapplied unique configurations on a particular thin client, although moreor less configurations may be stored in the configuration history (e.g.,in the configuration history folder 416). An administrator may be ableto select any configuration exposed as part of the configuration historyand successfully apply it. The configuration history may storeconfigurations for domain-joined and non-domain-joined users. Accordingto certain aspects, no two configurations in the configuration historymay be the same (e.g., if the exact same configuration file is beingapplied over and over on the same thin client, multiple entries of thesame configuration may not need to be stored within the configurationhistory and only the time stamp of the applied configuration may need tobe updated).

According to certain aspects, an option to apply the last successfullyapplied configuration may be allowed. In some aspects, an application(e.g., the configuration application module 404 and/or 506) for ITadministrators to create, view, and edit/update configuration files maybe provided to ensure ease-of-use in working with the number ofsettings/configurations by providing a human readable format for allsettings.

According to various aspects of the subject technology, a domain-joineduser may be able to access or set his/her preferred settings eitherlocally or from a network. Local settings may be specific to hardware,such as preferred graphics resolution, keyboard/mouse settings etc.Network level settings may be specific to user profile, the presentationlayer, and domain. This may allow users to log in to the same terminal,and give each user a personalized experience reflective of the user'spreferences for as long as the user uses that terminal.

Settings that may be applied on a client may fall into the followingcategories: 1) presentation layer settings (e.g., ICA, RDP, View, etc.);2) device settings; and 3) OS settings. In some aspects, all chosensettings by an administrator may be applied when a system of clients islocked and before users see their desktops upon logging in. In someaspects, the settings may be applied in less than ten seconds.

With respect to presentation layer settings, a user's presentation layerenvironment and settings (e.g., .rdp file) may be placed on the user'sdesktop. An administrator may be able to allow a thin client to boot ina way such that the administrator-selected protocol may only be used asa connection broker upon logging in. This may ensure that the USB stackssupport for View, RDP, and ICA do not conflict when using software suchas HP remote graphics (e.g., RGS).

The following presentation layer settings for RDC (e.g., based on RDC 7)may be supported:

-   -   screen mode id    -   use multimon    -   desktopwidth    -   desktopheight    -   session bpp    -   winposstr    -   compression    -   keyboardhook    -   audiocapturemode    -   videoplaybackmode    -   connection type    -   displayconnectionbar    -   disable wallpaper    -   allow font smoothing    -   allow desktop composition    -   disable full window drag    -   disable menu anims    -   disable themes    -   disable cursor setting    -   bitmapcachepersistenable    -   full address    -   audiomode    -   redirectprinter    -   redirectcomports    -   1redirectsmartcards    -   redirectclipboard    -   redirectposdevices    -   redirectdirectx    -   autoreconnection enabled    -   authentication level    -   prompt for credentials    -   negotiate security layer    -   remoteapplicationmode    -   alternate shell    -   shell working directory

The following presentation layer settings for ICA (e.g., based on ICA11.2) may be supported:

-   -   Citrix server IP/friendly name    -   Systray icon enable/disable    -   Logon mode    -   Window size    -   Color depth

The following presentation layer settings for VMWare View may besupported:

-   -   View connection server    -   Port

Secure connection

-   -   AutoConnect

According to various aspects of the subject technology, a primarypurpose of OS settings may be to ensure that the operating system is ina best possible state for an end-user to use and be productive, and foran IT administrator to reduce support calls/costs. Whenever applicable,the OS settings listed below may have volatile/persist options. Thevolatile option may imply that the respective setting does not persistupon reboot, while the persist option may imply that the respectivesetting persists upon reboot.

According to certain aspects, the following OS settings may besupported:

-   -   Date, Time, Time Zone, Additional Clocks (½) and respective time        zones and clock names    -   Network printer authorized for a specific user's access (may        involve installing custom printer driver)    -   Display size (e.g., 100%, 125%, custom size, etc.),    -   Graphics resolution    -   Display orientation (e.g., landscape, portrait, flipped        portrait, flipped landscape)    -   Extended monitor (e.g., duplicate on both monitors, extend on        the first monitor or the second monitor, display on only one        monitor, display on only the second monitor, etc.)

The following OS settings with respect to a web browser such as IE maybe supported:

-   -   Default IE homepage    -   IE favorites    -   Security levels for each IE zone (High/Medium/Low)    -   IE proxy settings—proxy server and port, with or without bypass    -   Kiosk mode

The following OS settings may be supported:

-   -   Default RAM disk size    -   Default aero theme, background, wallpaper, account picture    -   Completely Disable/Enable USB ports to run on client    -   Date/Time format (short/long)    -   Reset configuration (“wipe-out” existing configuration)    -   Location setting    -   System and Keyboard language    -   Computer name, domain name, user account name, custom password        for user, autologon for <username> with default password    -   Windows firewall on/off    -   Client side configuration manager import paramenters        -   FTP/HTTP protocol        -   IP address/friendly name of server        -   Apply last successfully applied configuration        -   DHCP option tags for ftp, server ip address, port, protocol,            vendor tag

According to various aspects of the subject technology, theconfiguration manager provided may provide two applications with userinterfaces: 1) a stand-alone application (e.g., the configurationapplication module 404 and/or 504) and 2) a control panel applet (e.g.,the user interface application module 1500 comprising the configurationcapture module 402, the retrieval module 308, the reset check module410, the configuration comparison module 412, the apply settings module414, and/or the configuration history folder 416.)

In some aspects, the stand-alone application may be used primarily forcreating and/or editing configurations (e.g., based on the settingslisted above), and also for viewing already created configurations. Thisapplication may run on various Windows operating systems, includingWindows 7 (Professional and/or Enterprise), WES7, Windows Server 2003,Windows Server 2008, and Windows Server 2008 R2. In some aspects, thestand-alone application, when running on a PC or a server based WindowsOS, may only run in create, edit, and view modes. In some aspects, whenthe stand-alone application is running on a Windows thin client, forexample, two additional functions may be exposed: 1) capture thin clientsettings and display them in a human readable format; and 2) applysettings from any configuration file.

According to certain aspects, the stand-alone application may supportconfiguration history functionality. For example, the last tensuccessfully created/viewed/edited configurations on a non-thin-clientdevice may be stored, although a greater number or a fewer number ofconfiguration histories may be stored. On a thin client device, thestand-alone application may leverage the last five successfully appliedconfigurations (e.g., same as what is exposed in the control panelapplet, as described below).

According to various aspects of the subject technology, the controlpanel applet may be used primarily for: 1) importing (applying)configurations from local and remote locations; 2) exporting currentsystem configuration to a local flash or USB drive; and 3)viewing/applying configurations stored in the configuration history(e.g., configuration history folder 416). For importing (applying), anadministrator may be able to provide the actual IP address or friendlyname of a FTP/HTTP server. For exporting, the configuration may beexported to a local storage or USB drive. However, the configuration maybe exported to other suitable locations. For viewing/applying, theconfiguration history may be exposed to an administrator per thinclient, as discussed above. Furthermore, options to specify custom DHCPoption tags may be available in this the control panel applet for vendortag, port, protocol, IP address etc.

Example of Implementation of Subject Technology

According to various aspects of the subject technology, a configurationmanager is provided that may be compatible with WES 7 clients, WES 2009clients, or other suitable clients. In some aspects, a user interfaceapplication module (e.g., the user interface application module 1500,which may also be referred to herein as Pyramid.exe) may exist underc:\Program Files\Wyse\ConfigMgmt, for example. In some aspects, thispath is ensured to be in the file-based write-filter exclusion list. Aconfiguration history folder (e.g., a snapshots folder) may exist underc:\Program Files\Wyse\ConfigMgmt, for example. A default xmlconfiguration file WES7Config.xml may restore to factory defaults. TheClientApp.dll and associated bitmaps may exist under windows\system32.According to certain aspects, the registry entries listed below exist:

- [HKEY_LOCAL_MACHINE\Software\Wyse\ConfigMgmt] - ″ActiveSnapshot″=″″ -″ActiveXML″=″″ - ″DefaultURL″=″Wyse\\WES7\\″ - ″Port″=″80″ -″Preserve″=″1″ - ″Protocol″=″http″ - ″ServerIP″=″″ - ″URL″=″″ -″Username″=″anonymous″ - ″Password″=″″ - “localXML”=”” -“DHCPServerTag”=”161” - “DHCPPathTag”=”162” - “DHCPUsernameTag”=”184” -“DHCPPasswordTag”=”185” - “DHCPProtocolTag”=”183”

In some aspects, the user interface application module may be madeavailable to all users. According to certain aspects, XML may bedesigned to describe data and to focus on what data is. The tags in XMLmay be not predefined. A user can define his/her own tags. XML may beself-describing, and may use a DTD (Document Type Definition) toformally describe data. According to certain aspects, the configurationfile may be in an XML format, and may be broadly divided into four maintags: 1) connections; 2) OS configuration; 3) device configuration; and4) common configuration.

In some aspects, the connections tag may describe data related to RDP,View type of connections, and other suitable connections. Examples ofRDP connections settings is listed below:

<allow_desktop_composition>0</allow_desktop_composition><allow_font_smoothing>0</allow_font_smoothing><audiocapturemode>0</audiocapturemode> <audiomode>2</audiomode><authentication_level>2</authentication_level><autoreconnection_enabled>1</autoreconnection_enabled><bitmapcachepersistenable>1</bitmapcachepersistenable><compression>1</compression> <connection_type>2</connection_type><desktopResolution>640×480</desktopResolution><disable_cursor_setting>0</disable_cursor_setting><disable_full_window_drag>1</disable_full_window_drag><disable_menu_anims>1</disable_menu_anims><disable_themes>0</disable_themes><disable_wallpaper>1</disable_wallpaper><displayconnectionbar>1</displayconnectionbar><gatewaycredentialssource>4</gatewaycredentialssource><gatewayprofileusagemethod>0</gatewayprofileusagemethod><gatewayusagemethod>4</gatewayusagemethod><keyboardhook>0</keyboardhook><negotiate_security_layer>1</negotiate_security_layer><prompt_for_credentials>0</prompt_for_credentials><promptcredentialonce>1</promptcredentialonce><redirectclipboard>0</redirectclipboard><redirectcomports>1</redirectcomports><redirectdirectx>1</redirectdirectx> <redirectdrives>0</redirectdrives><redirectposdevices>0</redirectposdevices><redirectprinters>0</redirectprinters><redirectsmartcards>1</redirectsmartcards><remoteapplicationmode>0</remoteapplicationmode><screen_mode_id>1</screen_mode_id> <session_bpp>15</session_bpp><use_multimon>0</use_multimon><use_redirection_server_name>0</use_redirection_server_name><videoplaybackmode>1</videoplaybackmode><connectionName>Pretty</connectionName> <domain>wyse</domain><full_address>10.150.2.24</full_address> <username>ayadav</username><winposstr>0,3,0,0,800,600</winposstr>

In some aspects, RDP connections (e.g., .rdp files) that are presentunder the document folder may be considered. In some aspects, .rdp filesstored anywhere else may be not considered for export. If theconfiguration file contains RDP connection entries, then except fordefault.rdp, all other .rdp files may be deleted from the documentfolder, and their respective link files may also be deleted.

Examples of VMware View connections settings is listed below:

<serverURL>http://10.150.5.5:443</serverURL><domainName>wyse.com</domainName> <UserName>admin</UserName><password>password</password> <DesktopName>desktop</DesktopName><desktopLayout>FullScreen</desktopLayout><desktopProtocol>0</desktopProtocol><loginasCurrentUser>0</loginasCurrentUser><brokerHistory>http://10.150.5.5:443</brokerHistory><mrBroker>xxx</mrBroker> <mrautoConnect></mrautoConnect><mruserName>admin</mruserName> <mrDomain>domain</mrDomain><screenSize>large</screenSize>

Examples of Citrix connections settings includes:

<citrixServer>10.150.102.53</citrixServer>

The OS configuration tag may describe data related to a web browser(e.g., IE), Firewall, Aero, additional clocks, wallpaper, and othersuitable data. For example, IE settings may include:

<internetExplorerSettings>   <homePage>www.google.co.in</homePage>  <internetZoneSettings>     <internetZone>medium</internetZone>    <localIntranetZone>medium</localIntranetZone>    <trustedSiteZone>medium</trustedSiteZone>    <restrictedSiteZone>medium</restrictedSiteZone>  </internetZoneSettings>   <internetProxy>    <proxyBypassServer>10.150.132.2</proxyBypassServer>    <proxyBypassPort>80</proxyBypassPort>    <proxyBypass>false</proxyBypass>   </internetProxy>  <ieFavoriteSet>     <favorite>       <folderName>abc</folderName>      <urlDescription>Telugu News Papers</urlDescription>      <url>http://www.sakshi.com</url>     </favorite>     <favorite>      <folderName>abc</folderName>       <urlDescription>WyseTechnologies</urlDescription>       <url>http://www.wyse.com</url>   </favorite>   </ieFavoriteSet> </internetExplorerSettings>

For example, firewall settings may include:

<windowsFirewall> <enableFirewall>true</enableFirewall></windowsFirewall>

For example, Aero settings may include:

<aeroFeature>   <enableAero>true</enableAero> </aeroFeature>

For example, additional clocks settings may include:

<clocks> <clock1>  <displayName>wyse1</displayName>  <tzregKeyname>IndiaStandard Time</tzregKeyname>  <enable>false</enable> </clock1> <clock2> <displayName>wyse2</displayName>  <tzregKeyname>W. Australia StandardTime</tzregKeyname>  <enable>false</enable> </clock2> </clocks>

In some aspects, the device configuration tag may describe data relatedto displays, mice, keyboards, networks, audio, power, and time zones. Insome aspects, display settings may include:

<display>   <displayDesktopBackground>     <file>myBackground.jpg</file>    <layout>center</layout>   </displayDesktopBackground>  <displayParams>   <manual>    <displayResolution>1024×768</displayResolution>    <displayRefreshRate>60</displayRefreshRate>    <colorDepth>16</colorDepth>     < displayOrientation>0</displayOrientation>   </manual>   </displayParams> </display>

In some aspects, the wallpaper is stored in a folder having the samename as the configuration file (e.g., an XML configuration file). Thus,if an XML configuration file named xyz.xml is exported, then a foldernamed xyz may be created in the same path as the XML file, and thewallpaper may be stored in that folder. In some aspects, if the xyz.xmlfile, for example, has been imported, then the folder and the XML filedoes not need to be deleted. If this is done, then exporting may causean issue, as the wallpaper may not exist anymore (the wallpaper wasapplied from the xyz folder). According to certain aspects, on a remoterepository in which a configuration file (either WES7Config.xml or<user>.xml) is contained, a folder by the same name (e.g., WES7Config or<user>) as the configuration file may be created. Changes such as a newwallpaper may be placed in this folder. In some aspects, the preferredformat may be JPEG, and the size of the JPEG file may be no more than 1megabyte to save on storage. However, other suitable formats and sizesmay be used. In some aspects, checking may be not performed on a JPEGfile size.

In some aspects, mouse settings may include:

<mouse>   <hideMouse>false</hideMouse>   <mouseSpeed>20</mouseSpeed>  <mouseSwap>false</mouseSwap>   <pointerTrail>5</pointerTrail>  <scrollLines>5</scrollLines>  <doubleClickSpeed>500</doubleClickSpeed>  <snapPointer>false</snapPointer>  <findMouseSonar>true</findMouseSonar><ClickLockTime>1200</ClickLockTime>  <MouseClickLock>false</MouseClickLock> </mouse>

In some aspects, keyboard settings may include:

<keyboard>   <defKBLayout>en-US</ defKBLayout >  <keyboardPref>false</keyboardPref>   <repeatDelayMs>2</repeatDelayMs>  <repeatRate>15</repeatRate>   <menuAccess>true</menuAccess>  <cursorBlinkRate>200</cursorBlinkRate>   <inputLanguage>    <langId>en-us</langId>   </inputLanguage> </keyboard>

In some aspects, the language identification is not displayed as countrycodes, but as human readable text.

In some aspects, the time zone settings may include:

<timeZone>   <standardName>India Standard Time</standardName>  <daylightName>India Daylight Time</daylightName>   <bias>−330</bias>  <daylightBias>0</daylightBias>   <standardBias>0</standardBias>  <timeZoneKeyName>India Standard ime</timeZoneKeyName>  <dynamicDaylightTimeDisable>false</dynamicDaylightTimeDisable></timeZone>

In some aspects, the network settings may include:

<networkSettings>   <ipAddress>     <dhcp></dhcp>     <dnsAddress>      <staticDNS>         <dns1>10.150.2.10</dns1>         <dns2></dns2>         </staticDNS>       </dnsAddress>     <winsAddress>      <wins1> </wins1>       <wins2> </wins2>     </winsAddress>  </ipAddress> </networkSettings>

In some aspects, the audio settings may include:

<audioSettings>  <lineoutMute>false</lineoutMute> <lineoutVolume>0.1</lineoutVolume>  <micMute>false</micMute> <micVolume>0.5</micVolume> </audioSettings>

In some aspects, the power settings may include:

<powerSettings>   <powerPlanDefault>balanced</powerPlanDefault>  <dimdisplayOnBattery>1 minute</dimdisplayOnBattery>  <dimdisplayPluggedIn>2 minutes</dimdisplaypluggedIn>  <offdisplayOnBattery>2 minutes</offdisplayOnBattery>  <offdisplayPluggedIn>5 minutes</offdisplayPluggedIn>  <sleepcomputerOnBattery>Never</sleepcomputerOnBattery>  <sleepcomputerPluggedIn>Never</sleepcomputerPluggedIn></powerSettings>

According to certain aspects, the “balanced,” “power saver,” and thecustomized power plans may be supported.

According to various aspects of the subject technology, the common tagmay describe extra and/or miscellaneous data. An OS type element mayspecify whether a configuration file is for WES 7, WES 2009, WTOS,Linux, or some other suitable operating system.

According to certain aspects, a reset tag may control a wipeout feature.If the reset tag value is set to “1,” then a default configuration file(e.g., WES7Config.xml) may be applied first. The .rdp files andshortcut, in addition to the IE favorites may be deleted. In someaspects, vmView registry settings may be cleared. After this, the<user.xml> or global configuration file may be applied (e.g.,WES7Config.xml). This option can only be set from a server side (e.g.,server 112) user interface. An example of the reset tag settings isshown below:

<common>     <commonSettings>       <OSType>WES 7</OSType>      <reset>0</reset>     </commonSettings> </common>

According to certain aspects, a schema language such as XSD can be usedto express a set of rules to which an XML configuration file may conformin order to be considered valid according to that schema. For example,the XSD file may be named as WESTypes.xsd. The XSD file (e.g.,validation file 406) may be used to validate the data present in the XMLconfiguration file (e.g., S306 a and/or S306 b). The XSD file may alsodefine as to what value a data can have and also the type of data. Forexample, an inquiry may be how to tell what values are valid for agatewayCredentialsSource. The following line indicates how thegatewayCredentialsSource element is represented:

<xs:element name=“gatewaycredentialssource” type=“gatewaycredentialssourceType” minOccurs=“0”/>

The gatewaycredentialssourceType may be a custom defined type and may bedefined below:

<xs:simpleType name=“gatewaycredentialssourceType”>  <xs:restrictionbase=“xs:integer”>   <xs:enumeration id=“Ask for password(NTLM)”value=“0”/>   <xs:enumeration id=“Smart card” value=“1”/>  <xs:enumeration id=“Allow me to select later” value=“4”/> </xs:restriction> </xs:simpleType>

The above definition may state that the gatewayCredentialsSource caneither have 0, 1, or 4 as its value in XML. Any other value may resultin failure of validation of the xml configuration file.

According to various aspects of the subject technology, the followinguse case scenarios may arise for the control panel applet (e.g.,Pyramid): 1) USB pen drive transfer (e.g., for a small organization);and 2) stand-alone/remote mode. In the USB pen drive transfer scenario,a company may be a small unit and may be limited in monetary resources.In this case, the control panel applet can be used to configure devices.For example, an administrator may configure a device thin client withspecific requirements. The administrator may want to deploy this to tenother thin clients. Thus, the administrator can open the control panelapplet, export the configuration to a USB pen drive, plug that USB driveto another thin client, and import the configuration using the controlpanel applet.

In the stand-alone/remote mode scenario, multiple clients may need to beconfigured from a remote repository. In this scenario, an administratormay select the remote option (e.g., as shown in FIG. 15A) and fill inthe data related to remote IP and remote path. The administrator mayselect either FTP, HTTP, or HTTPs and click on a “Download and Apply”button. These settings may be saved after clicking on the “Download andApply” button. The “Persist settings on reboot” may be checked if theconfiguration is to be applied after every boot of the client device102. In one example, a default remote path is <ftproot>\Wyse\WES7.

According to certain aspects, a stand-alone application (e.g., theconfiguration application module 404 and/or 504) may be provided thatgenerates a configuration file from scratch. This application can beused to edit an existing configuration file as well. The created/editedconfiguration file can be used to apply the configuration either instand-alone mode or in remote mode.

According to certain aspects, the retrieval module 408 (e.g., which mayalso be referred to herein as Hagent_Utexe) may be an engine that thatruns at startup of a client device 102. This engine may look at theregistry values under [HKEY_LOCAL_MACHINE\Software\Wyse\ConfigMgmt] orother suitable registries. Depending on the protocol, the engine mayimport configurations. If the protocol is local, then an ActiveXML maymention a path of an XML configuration file to be applied. If the XMLconfiguration file exists at that path, then configurations may beimported.

According to certain aspects, if the protocol is FTP or HTTP, then thefollowing order may be used for obtaining the XML configuration file:

DHCP options (e.g., Method B-1)

UI configured settings (e.g., Method B-3)

Local default xml file (e.g., Method B-4)

The engine may look at the below DHCP tags below:

DHCPServerTag=161 DHCPPathTag=162 DHCPUsernameTag=184DHCPPasswordTag=185 DHCPProtocolTag=183

According to certain aspects, except for the DHCPServerTag, all theother tags may be of type String. The DHCPServerTag may be configured asan “IPAddress” type.

If the foregoing DHCP options are not configured, connection fails, or aconfiguration file does not exist on the server, then the engine mayfail over to the remote settings set from the control panel applet. Ifthe remote settings are not configured (e.g., from the control panelapplet), the connection fails, or the configuration file does not existon the server, then the engine may fall back to the locally storedWES7Config.xml.

For example, on a server, using IIs, suppose an administrator setsCAPyramid as the virtual directory. Then the engine may expect aWyse\WES7 folder to be existing under C:\Pyramid. Thus, if HTTP or HTTPsis selected and if login is local and no path is specified, then theengine may look for a configuration file named WES7Config.xml underC:\Pyramid\Wyse\WES7. If the path is specified, then the engine may lookfor WES7Config.xml under C:\Pyramid\Wyse\WES7\<path>. In the case of adomain login, the engine may look for <user.xml>.

In some aspects, if no protocol is mentioned in the DHCPProtocol option(e.g., 183 by default), then HTTP may be considered. In some aspects, ifuser name and password are not mentioned in the DHCP option tags, thenanonymous login may be considered. According to certain aspects, theport may be considered depending on the protocol. The port may be 21 forFTP, 80 for HTTP, and 443 for HTTPS, although other port values may beused.

According to various aspects of the subject technology, in a scenario ofa local user and a domain user, the user may have either logged inlocally or performed a domain log in. In some aspects, this scenario maybe tested only in the remote mode. In some aspects, if a user performs alocal log in, then the configuration file downloaded from the remoterepository server may be WES7Config.xml. In some aspects, if the userperforms a domain log in, then <username>.xml file may be downloaded andapplied.

An example of an XML configuration file is shown below:

For example, a module (e.g., a configuration generation module 430, aconfiguration capture module 402, a configuration application module404, a retrieval module 408, a reset check module 410, a configurationcomparison module 412, an apply settings module 414, an applicationmodule 422, a driver module 424, an operating system module 426, a userinterface application module 1500, a configuration application module504, an operating system module 508, or any other modules) may beimplemented as electronic hardware, computer software, or combinationsof both. In one aspect, a module(s) may be an apparatus since amodule(s) may include instructions encoded or stored on amachine-readable medium, on another device, or on a portion thereof. Inone aspect, a module(s) may be software (e.g., an application, asubroutine) stored in a machine-readable medium and executable by aprocessing system or a processor. In another aspect, a module(s) may behardware (e.g., machine-readable medium encoded with instructions, apre-programmed general-purpose computer, or a special purpose electronicor optical device).

Various modules may reside in one machine or in multiple machines. Inone example, modules for the server side (e.g., a configurationapplication module 504, an operating system module 508, etc.) may belocated in one server or spread over multiple servers. In anotherexample, modules for the client side (e.g., a configuration generationmodule 430, a configuration capture module 402, a configurationapplication module 404, a retrieval module 408, a reset check module410, a configuration comparison module 412, an apply settings module414, an application module 422, a driver module 424, an operating systemmodule 426, a user interface application module 1500, etc.) may belocated in one client device or spread over multiple client devices.

In one aspect of the disclosure, when actions or functions are describedas being performed by a module or a component (e.g., creating,retrieving, applying, capturing, validating, storing, attemptingretrieval, checking, comparing, obtaining, facilitating, loading,parsing, installing, resetting, stopping, registering, adding,disabling, enabling, locating), it is understood that such actions orfunctions are performed by the module or the component directly orindirectly. As an example, when a module is described as performing anaction, it is understood that the module may perform the action directlyor may perform the action indirectly, for example, by facilitating suchan action. For instance, when a configuration file is described as beingobtained by a module, it is understood that the module may obtain theconfiguration file indirectly by facilitating obtaining theconfiguration file. In some aspects, it is understood that certainfunctions can be divided into different modules to be performed (e.g., afunction for an apply settings module 414 can be performed by aretrieval module 408, etc.).
